d9826f6043 SimplifyBranch: don't leave an empty block after merging two basic blocks 
Although empty blocks are cleaned up at the end of every Simplification pass, it's not legal SIL to have empty blocks and subsequent simplification passes may crash because of this.

8223b3e210 MandatoryPerformanceOptimizations: fix some problems with inilning 
* don't inline functions if it's not possible - by checking `SILInliner::canInlineApplySite`
* fix stack nesting after inlining a `begin_apply`

625619ee17 SIL: add a bare attribute to global_value 
The `bare` attribute indicates that the object header is not used throughout the lifetime of the value.
This means, no reference counting operations are performed on the object and its metadata is not used.
The header of bare objects doesn't need to be initialized.
